Machine for hook-heading spikes by one motion



JONATHAN BEARDSLEY, OF TRENTON, NEW JERSEY.

MACHINE Foa Hook-HEADING sPIKns BY oNE MOTION.

Specicaton of Letters Patent No. 6,0075, dated January 9, 1849.

To all whom t may concern.' f

Be it known that I, JONATHAN BEARDSLEY, of' the city of Trenton, county of Mercer, State of New Jersey, have invented a new and Improved Mode of Constructing a Machine for Heading Rivets, Bolts, Spikes, or Nails; and I do hereby declare that the following is afull and exact description of the same,

reference being had to the annexed drawings, forming a part of this specification.

Figure 1. is a perspective view of the whole machine. Fig. 2, is a section showing the carriage, punch rod, punch &c., &c.

A, Fig. 1, is adriving wheel, attached to the shaft B, to which the power is applied, C, a lcrank and arm that moves the carriage D, in which is placed the punch rod E. Vor

vmore clearly seen at B, Fig. 2. a

F is a roller against which the projection e. Fig. 1. of the punch rod presses and which gives it a properl lateral movement to bend over the end of the rod held in the die t0 form the spike head.

G is a screw for regulating the motion of the punch rod B; H, the punch; I, the die or jaws in which the object to be headed is placed; J, J, two levers. acting with an elbow movement, and'receiving their impulse from the motion of the carriage for the punch rod. These operate upon a shaft on which is a cam L, which lifts the die or jaws I, by the lifting piece K. and the jaws being forced together at w v Fig. 1. sever the spike from the rod.

M is a rod attached at one end to the lifting piece K and by the other to a spring N.

a is the place of the joint of the rod from the crank with the-carriage.

Z; is a pin (better seen at a Fig. 2,) on which the punch rod moves on a pivot.

F, is an orifice in the punch rod for the purpose of taking the punch out; G, the set screw; c, the place where the crank rod connects with the follower.

At the end of the frame work opposite that of the driving shaft is a strong piece of metal in which is placed thedie or jaws which hold the wire or the rod to be headed. This metal is marked P. Fig. 1. The punch H Fig. 1. or E Fig. 2. has by the time the projection 0. strikes the roller, moved so far, that its end has passed a little beyond the rod to be headed, which projects from the die or jaws at I. Fig. 1. Then the ylateral `movement caused by the .roller makes the punch turn the end of the rod over in the direction of its movement, the punch mov ing forward strikes with its broad face upon therod thus bent with a strong blow against thedie' I. (which are closed at the time) and thus produce the flat turned head, or half head, such as are seen upon railroad and similar spikes, thus L.. The crank motion then immediately withdraws the punch,

, and'at the same time the rod is again pressed forward by hand for another head which is produced inthe same way, in rapid succes` sion. If it is desirable to have a full disk head thus I- the set screw G, Fig. 1, may be used to place the punch on an exact line with the wire or rod to be neaded, and in this casethe roller does not touch it. A conveX head or any other according to the form of the punch or die may be made in this way. When the punch rod has full play the spring b, Fig. 2, throws it back to its diagonal position relative to the wire when it is drawn back from the operation of the roller.

Other contrivances beside a roller may be used for'producing the same effect, suc-h as a toggle joint or wedge &c., but -I think the roller' preferable as having less friction and being less liable to get out of order. By this method of construction, great facility and accuracy is obtained in the heading of spikes, bolts, &c., the whole operation being performed by a single and very simple movement and herein I claim a great advantagev over all others now in use.

The method of holding the wire and the levers and camsv below for moving the die and cutting o' the rod are now in use and I JONATHAN BEARDsLEY.-
